In LinkedIn you can easily add the company for which you work in the profile. If previously your professional seo agency didin’t have a page on Linked in, going through these steps will allow you to connect to that company’s LinkedIn page.
Go to www.linkedin.com
Log in (or create an account if you don’t have on already)
Hover over (or click on) Profile at the top of your home page and select Edit Profile.
Scroll down to the Experience section and click the Add a position link. Or if you already have a position entered, but did so prior to your company having a page, you can click Edit and change the position there.
Type in your Company Name and look for your company’s information in the list.
When the company name shows up, just go ahead and select it.
Enter the remaining fields.
Click Save Changes.
